DANIEL J. ROGERS AND STUART A. DAY, OF STAUNTON, VIRGINIA.

STOVE.

T 0 all whom it may concern:

Be it known that we, DANIEL J. ROGERS and STUART A. DAY, citizens of theUnited States, residing at Staunt-on, in the county of Augusta and Stateof Virginia, have invented certain new and useful Improvements inStoves; and we do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

Our invention relates to stoves and particularly to the construction ofthe front and bottom grates and the fire back.

The principal object of the invention is the production of a grate orfire back having means whereby it may be reduced in size longitudinallyor transversely or both where by either one of these parts may be madeto fit stoves having difierent sized fire boxes.

A further object of the invention is to provide means whereby theexpansion and contraction of the fire back may be accommodated withoutdamaging the plate by bulging, as frequently occurs when the fire isextremely hot. v

W'ith the foregoing and other objects in view, the invention consists ofcertain novel features of construct-ion, combination and arrangement ofparts as will be more fully described and particularly pointed out inthe appended claim.

In the accompanying drawings, Figure l is a top plan view of the bottomgrate; Fig. 2 is a detail side elevation thereof; Fig. 3 is a frontelevation of the upper or front grate; Fig. i is a front elevation ofthe fire back; Fig. 5 is a detail rear elevation thereof; Fig. 6 is adetail vertical section on the line 6-6 of Fig. 4. Fig. 7 is atransverse section of the grate with the parts assembled. Fig. 8 is alongitudinal section of the same.

Referring more especially to the drawing, we have shown a bottom gratecomposed of longitudinal bars 1 and cross bars 2, which are integrallyconnected therewith and, as usual, the grate is made of a singlecasting. The ends of the longitudinal bars extend considerably beyondthe end cross bars 2 and are provided with transverse notches 3, whichweaken the ends and provide spaces whereby a cold chisel may be used tocut the bars off to the desired length. Between the first twolongitudinal bars on either side,

the cross bar is notched at 4 and each outside longitudinal bar isnotched, as at 5, for a similar purpose. In this manner the grate may bereduced in size so that it will fit any fire box and will be reversibletherein having no revolving pintles on its end to prevent the adjustmentmentioned.

The front grate is shown at 6 and at each end is provided withlongitudinal notches 8 and transverse notches 9, whereby the depth andlength of this member may be adjusted as described for the bottom grate.The back is shown at 10, and is provided with a lateral flange 11 on itsupper side which will overhang the oven of the ordinary cook stove. Theback of this member is provided with longitudinal notches 12 andtransverse notches 13 for the purpose described for the bottom grate.The longitudinal notches are spaced from the bottom of the back and thetransverse notches are arranged at one end only and extend throughoutthe overhanging flange in continuation of the transverse notches on thebottom.

At the opposite end of the back, we provide a recessed seat 14intermediate the width of which we provide a longitudinal slot 15adapted to receive a securing bolt 16, whereby an extension plate 17 maybe secured in the seat and project beyond the end of the back, ifnecessary. In operation, the back is cut off to the required degree toproperly fit the stove and the extension plate is applied to the seatand engaged behind the lug on the stove, so that disengagement ispermitted. This plate is preferably made out of some thin sheet materialsuch as steel, which will have suflicient flexibility to compensate forthe expansion and contraction of the back 10, so that, when the latteris acted upon by the heat, the plate 17 will flex and thereby preventthe bulging of the back 10.

Each of the members 6 and 10 are provided with ribs 18 on their facewhich prevent the coal from crowding in the fire box and thus afford ameans whereby the draft through the stove can be properly maintained.

From the foregoing description taken in connection with the accompanyingdrawings, the construction and operation of the invention will bereadily understood without requiring a more extended explanation.

Having thus described our invention, What We claim is A structure of thecharacter described comprising a bottom grate with longitudinal andtransverse cross bars each having breakable oppositely disposed endportions, a front grate provided With intersecting longitudinal andtransverse breakable end portions to adapt it for adjustment to fit thebottom grate, a solid back plate having an overhanging flange to connectWith the oven of a stove, said back plate being also provided Withcontinuous longitudinal breakable portions having intersectingtransverse breakable portions at one end thereof, and having at itsother end an enlarged transverse recessed seatt'ormed therein providedWith a longitudinal slot, an extension plate having inclined edgesslidably mounted in said recessed seat and flush with the surface of theback plate, a bolt inserted through the slot and extension plate so asto adjust the extension plate longitudinally of the back plate, saidextension plate being longer than the recess so as to project therefrom,and said back plate having ribs on its outer face.

In testimony whereof We have hereunto set our hands in presence of twosubscribing Witnesses.
